I CORRUGATED VESSEL.

To all whom it may concern Be it known that I, WILnnmr KticHLING, a subject of the King of Prussia, residing at Berlin, Germany, have invented certain new and useful Improvements in Corrugated Vessels, of WhlCh the following is a specification.

My inventionrelates to corrugated walls and vessels, such, for example, as transformer tanks, andthe objectof my invention is to provide a corrugated wall with a portion better adapted to be readily, and firmly attached to an adjoining wall or other ody than is a simple corrugated edge.

It is fairly obvious, and has long been understood, that a joint made to the edge or side or both of a corrugated wall is unsatisfactory and diflicult to make, and various expedients have already been resorted to to secure a better joint between a corrugated wall and an adjacent body. In carrying out my invention, I propose to modify the end of the corrugated wall in a novel manner, so that it may be fairly readily welded or otherwise attached to another body, as a band or another portion of the vessel; preferably I carry the modification so far as to produce an attaching edge which is more nearly straight than the unaltered corrugated edge of the sheet; j

*An application of my invention will be understood by reference to the accompanying drawings; this application is described in detail below. Structures embodying my invention have substantial advantages over those structures produced prior to my invention; among these may be enumerated the following: The seam is ready of access but is within the outlines of the vessel and protected from blows. The slanting of the ends of the corrugations renders the cover, or any other part of the structures adjacent the ends of the corrugations, of ready access.

Adjacent the attaching edge, parts of the corrugated metal extend inwardly, thereby afl'ording additional opportunity for the exchange of heat between the walls of the Specification of Letters Patent.

,. My invention may be embodied in ;corrugated walls or vessels 'made of either cast or sheet metal. It will-more readily be'un-- a sheet metal corrugated wall; for the pur poses of this specification I shall call the portion 1, 2, 3, 4 a single corrugation. Taking such a sheet I bend the end portion of Patented Nov. v28, 1916.. Application filed June 5, 1914. Serial No.843,1 57. i

each corrugation to be treated at an angle to the wall, as illustrated in Fig. 2; pr'eferably, this portion is so selected that theiterminal edges of the corrugations make an angle of approximately 45 degrees with the extent of the corrugation. Thus it will be seen that the point 3 of Fig. 1 has been bent inwardly to the point 3' of Fig. 2 and that the terminal edges 15'and-2.5 of thiscorrugation, since the distance 3-5 has been chosen approximately equal to the depth of the corrugation 1, 2, 3, make angles of approximately 45 degreeswith the extent of the corrugation. After each of the corrugations to be treated has been bent in this way, I prefer to proceed to jpin together a portion of each of the faces 1. 3L 5 and 2,-.3',-5, to form a ridge ,3, 5, 6 projecting away from the bent portions. producing a shape something like that illustrated in Fig. 3. From this figure it will be seen that the portion 3, 5. 6 of each of the faces 1, 3. 5 and 2, 3, 5 have been made to substantially enga e each other. These surfaces 3, 5, 6 may e attached together, for example by weldingthem along their meeting edges 3, 6 and 5,

'6, if desired. Now. the extent of the engaging surfaces 3', 5, 6 relative-to the surfaces 1, 3, 5 and 2, 3', 5 1s more or less 1mmaterial. It is quite possible to weld or otherwise attach a band to the edge of which rugations, 1, 6, 2, etc.,t'o a band, an adjacent wall or any other body ofiering a coiipera tive surface. In Fig. 4 is shown such a structure welded to a band 7. It will be noticed that the edge 3', 6 may also be attached to the band 7 in this case, theridge 3', 5, 6 providing an additional point of support for the band 7.

When producing a structureembodying my invention from sheet metal, the steps I have'outlined may be followed, though the .process itself forms no part of my invention which I propose to claim here. If the wall.

is to be of cast metal the wall may be ,cast

into the desired shape at first instance."

Especiallyin a cast wall it may be desirable to leave oft the portion 3, 5, (3 entirely, although the attaching edgeis given the form 1, (3, 2 of Fig. 3. It will be understood that in the case of cast structures well as in sheet metal structures, the angles 1, 5, 4 and 1, 6, 2 and (3, 5, 3 (orG, 5, 4) may be either greater or less than those illustrated in the drawing and that more or less of the total numbrof corrug: tions may be treated;

lVhile I have described the principle of my invention and the best mode I have contemplzited for applying this principle, other modifications will occur to those skilled in this art and I aim in the appended claims to cover all modifications which do not involve a departure from the spirit and scope of my invention.

lVhat I claim as new and desire to secure by Letters Patent of the United States, is, 1. A corrugated wall, the ends of some'of the corrugations being bent at an angle to the wall and located within such corrugations, and a body attached to the free ends of such bent portions.

2. A corrugated wall, the ends of some of the corrugations l ving bent at an angle to the wall and located within such corrugathe wall and located within such corrugations a portlon of the adacent faces of each bent portion engaging with each other to fol-ma ridge projecting away from those bent portions, and a body attached to the free ends'of such bent portions.

4. A corrugated wall, some of -the corrugations terminating at an angle to their eX- tent and each of such corrugations being provided with a portion located within such corrugations adjacent the ends thereof and inclosing the space within such corrugations.

5. A corrugated wall, some of the corrugations terminating at an angle'to their extent and each of such COI'lLllgtltlOIlS being provided with a portion located within such corrugations adjacent the ends thereof and inclosing the space within such corrugatioi'is, and a body attached to the free edges of suchinclosing portions.

-6.' A corrugated wall some of the corrugations terminating at an angle to their extent and each of such corrugations being provided with a portion having generally triangular outlines joined at two edges to the terminal edges of the corrugation and fornunga cap for the end ot such corrugation.

In witness whereof- I have hereunto set- .my hand this 19th day of May, 1914.
